which is adaptedto burn any suitable fuel for supplying the necessaryheat. ,The invention consists in-the features of novelty that arehereinafter described with referenceto he accompanying drawings I e apart of'th-is specificationandinwhlch F tire}. is a sectionalelevationiof a gas waterkheater embodying all of the several features ofthe invention in their preferred forms'.- Fig, 2 a perflpective View ofthe spreader in its preferre form; Fig.3,isa 'plan view'ef a spreader ofmodified'construction, ,Figs at and 5 are axial sections there of thelines4;4 and '5 5, Fig, 3, looking into the direction of the arrows,respeclyrepresents' a -tank,c'al-led theboiler, 2 a cold water supplypipe, 3 a circulating pipe, and 41 the SBIVICQ pipe. Preferabl I thecoldwater supply pipe extends throng I the crown of the Indexanddownward thereinto, terminating at any desired distance from thebottom, 5, thereof, and preferably this service pipe extends through the"crown of the boiler and terminates near the top thereof. The upper endof the circulating. pipe, 3, communicates with the service pipe, 4, nearthetop of the boiler; As. before 111 timated, the boiler forms in fact areservoir through which a circulation is maintained when water is nothein 'drawn ofi from the service ipe and, in ad 'ition thereto, a storage tan m which the water is stored as it is heated, s'o that when wateris'drawn 'oif fromthe, service e it will be taken from theup er part 0 te boiler, where it is of" hest temperature. The lower end of thecirculatingpipe, 3, communicates with the 'top'of the spreader, 6, and.the bottomof the spreader communicates with one end of" a circulat"-pipe,.'7 the other end of which extends t rough the bottom, 5, of theboiler andp conunun lcates with the interior thereofi The spreader, :6,and the eirculat ing'pipe, 7,. are-contained within a combus-V tionchamber, 1", which is formed-by a down- Wa-rdj extension, 1.,- ofthejboil'er and the I lower end of this extension rests upon a sup!portin ring, 8, which issu'pporte by'the re 'ngjrms, 9, of a foot orpedestal, 10. "e spreader is" made. of what maybe; called two lates,llf'and 11",, of circular outline, .altliough they, are eas fi i ntegraHyand connect'edat their peripheries by ,a portion of; 110

the casting comprising them, so that they are spaced and held apart. Thetwo plates are of substantially concavo, convexj shape and arranged withtheir concavo sides uppermost, so as to'leave between them a comparetively thin internal chamber or'passage fi in which the'water is spreadout ina thin .film or layer with a view to facilitate itsbeing heated.

The plates, 11 and 11*, are continuous, that is to say they arewithoutany open ings or perforations through which water can pass, so that theupper plate, 11, being concave, or dished, on its upper'sicle, formsv adrip pan in the manner and forthe purpose herein after described. Thespreader "hasalsoaplurality of passa es, 12., above the-spaceo-rchamber, 6", whic connect and afiord communication between the outerportion' of said chamber, 6", at different points, and the lower end ofthe circulating pipe, 3.

There may be any desired number of these passages and they arepreferably formed in, or rather are afforded by a plurality ofhollowarms or branches, 13, of the integral. casting which comprises theentire spreader and its, several features, which branches jointheperipheries of the plates, 11' and 11",

' f at distantpoint, whence they preferably extend upward and inward andcometogether 'in-a hollow spud, lhwhich is preferably in- .terna-llyscrew-threaded and engages the correspondinglyexternally threaded end ofthe circulating pipe, 3. Any desired number of these hollow'branches,may be'used and they maybe inclined upward and in 'ward, and radiateafter the manner of the spokes of a wheel, as shown in Figs. 1 and 2, or.they may lie in a plane perpendicular to the axis-of the spud, 14, orhorizontally,

as shown in Figs. 3, 4 and 5. Butprefer-v ably, they incline upward andinward betop wall, while in theform sliownin Figs. 7

3, 4 and 5, the branch in whichthe passage way, 12, is formed is a mererib, 13 on the top of the plate, 11, of-the chamber 6". 'In any eventthe spreader 'is belowand directly in the vertical line of a flue, 15,forthe purpose hereinafter described. With this ar'-' rangement,assuming that no'water is being drawn-ofi' from the service pipe, as thewa ter enters the spreader through the'circu latin pipe, 7, it will. bespread out in the chain er, 6", of the spreader'in a thin film or bodyand as it becomes heated it will rise upward in the space or "chamber6", and .pass into the hollow branches, 13, thence upward through saidbranches into the lower end of the circulating pipe, 3, thence up partof the chamber.

ward-through said pipe into the servicepipe, 4, and thence'downward'throughthat portion, 4, of the service pipe which ex tendsfrom its point of communication with the circulating pipe, 3, to theboilefithence downward into and through the- "boiler thence downwardinto and through the cir culating pipe, 7, and 'so on, continuing in acomplete circuit so that all of the water in Y the boiler becomes highlyheated. When the service pipe is o ened to draw off water I it will besupplied rom the. upper part or the boiler, where it is hottest, and-1t1s in order to prevent cold watersupplied through the pipe, 2, fromdirectly entering the service pipe, 4, that said pipe is burned downwardto a leyel near. the

o/ttom of the boiler;

It is found in actual; practice that a. spreader constructed in themanner above described-is hightly eflicient, the reason'for this being'thiitits construction is such' that the water is at no point'compelledto flow contrary to natural physical laws. The under side'of the sreader has a large area 'which is subjected to the direct-action of theflame, and the effect of beating themter is to causeit'to flow upwardand 'downward in all directions from the centeriof thecirculatingchamber, 6". It is manifest that .the' effect of this chamberis to form a pasin the direction of the flow, and conse-' .quently, thevelocity of the'llow will beleast i atthe extreme outer portion, of thechamber. It is at this point that the combustion'conies therefore,will'be greater than at any other Still obeying the natural physicallaw, the water thus heated will pass upward and inward, through thepassages, 12, which are of amplecapacity, and

. .05 'sageway of constantly- 1ncreasj1ng capacity 5 the nearest tobeing'complete, and the heat,

enter the lower end of the-circulating pipe,

3. A reversal of some of the features of this construction are shown inmy former Patent, No. 1,013,581, granted Jan-,2, 1912,

- and while the arrangement there shown gives fairly satisfactoryresults, ityis nevertheless found that in actual practice the arrangementshown in the present application 'is of the greater efiiciency.

As before stated,the, spreader is contained 7,

within the combustion chamber and in order toutilizethe hatof theproducts of comchamber, a flue, 15, is arranged so that its lower endcommunicates with'its combllB- I tion chamber, 1?, directly over thespreader, whence it extends upward completely through the boiler, and atits upper end is 125 bustion into a suitable flueor pipe-by which openfor the escape of the products of comthey are carried off and ultimatelydischarged, and the circulating pipe, 3, is arrangedconcentrically'within this flue. The combustion chamber also completelylinbust'ion after'escaping' from 'the combustion nmate "closesitlieburner, -16,. which, is. preferably in 2 and of with its concave sideuppermost, and this is important in that when soyarranged it serves as adrip'cup for catching andv retaming the water of condensation whichtrickles: down the circulating. pipe, 3, and

the interior of the flue, 1'5. Otherwise this water wouldfall upon thefloor and in some instances would fall upon the burner and the verticalbranch, 17, of the "circulating pipe, 7, which fits the pipe snugly but1 loosely enough to permit of the-vertical ad justm'ent of the burner.The lower end "of the pipe, 17, screws into the vertical branch of anelbow, 18, into the horizontal branch of which screws one end of a shortpipe,-

19, the other end of which screws into the horizontal branch of anelbow, 20, into the vertical branch 0f which screws the lower end of themain'vertical branch of the circulating pipe, 7. The periphery of theburner is notched to engage the vertical pipe,'7, and the pipe, 19, isprovided Wltll.

' right and leftthreads and .is of such length 7 that when turned in theproper direction the, burner will be clamped between the vert1-- calbranches, 7 and 17,.of the circulating pipe, whereby it is adjustablyheld ported. J v
